Abstract (2. Language):
Objective: The aim of this study was to examine the effect of surgical extraction of impacted mandibular on the
Temporomandibular Opening Index (TOI) in patients with temporomandibular disorders (TMD).
Materials and methods: Ten patients (2 males, 8 females; age range 21 to 33 years) with TMD undergoing surgical
extraction of the impacted third molars were recruited in this study. Before the surgical operation and three
months after the surgical operation the clinical stomatognathic examinations were carried out by the same dentist,
specialized in the stomatognathic physiology, who also determined TOI (in percents) according to the following formula:
Passive opening (mm) – Maximum voluntary opening (mm)
TOI = x 100
Passive opening (mm) + Maximum voluntary opening (mm)
Results: Three months after surgery, a marked improvement in signs and symptoms of TMD, as well as a statistically
significant (p <0.01) decrease in TOI was observed.
Conclusion: The TOI seemed to be a good assessment criterion of limitation in mandibular mobility

Abstract (Original Language):
Amaç: Bu çal›flman›n amac› alt üçüncü büyük az› difllerinin cerrahi çekiminin temporomandibular rahats›zl›¤› olan
olgularda temporomandibular aç›lma indeksine etkisini araflt›rmakt›r.
Gereç ve Yöntem: Alt üçüncü büyük az› difllerinin cerrahi çekimi gereken temporomandibular rahats›zl›¤› olan 10
hasta (2 erkek, 8 kad›n; 21 ile 33 yafllar› aras›nda) bu çal›flmaya al›nm›flt›r. Cerrahi çekimden önce ve cerrahi çekimden
3 ay sonra bu hastalar›n stomatolojik muayeneleri ve temporomandibular aç›lma indeksleri ayn› hekim taraf›
ndan yap›lm›flt›r.
Temporomandibular aç›lma indeksi flu formülle tayin edilmifltir:
Pasiv aç›kl›k (mm) – Maksimum istekli aç›kl›k (mm)
TOI = x 100
Pasiv aç›kl›k (mm) + Maksimum istekli aç›kl›k (mm)
Bulgular: Cerrahi çekimden 3 ay sonra temporamandibular rahats›zl›¤›n semptomlar›nda ve temporomandibular
aç›kl›k indeksinde anlaml› bir azalma görülmüfltür.
Sonuç: Temporomandibular aç›lma indeksi mandibular hareketlerinin s›n›rl› oldu¤u durumlarda iyi bir de¤erlendirme
kriteri olarak kullan›labilir.
